| Abstract: | The ore structure of Daling Mine is complex in Jilin Nickel Industry Corporation, it is typical low grade difficulty mining deposit. After determined the mining method, the study of stopping ore fall's way is very important to whether stopping successfully. This paper emphasized the stopping ore fall, its guidance to future production and similar mines. |
